Cortisol, a hormone released by the adrenal glands, follows a natural diurnal rhythm, peaking in the early morning and tapering through the afternoon and evening. Under normal conditions, cortisol levels peak in the early morning, helping regulate energy, blood pressure, immune response, and stress adaptation.
This test measures the free biologically active cortisol in a single saliva sample collected in the morning offering a noninvasive way to assess baseline adrenal function and identify possible HPA axis dysregulation. This single salivary test offers a convenient screening tool in both preventive care and follow-up settings.
